Menlo Systems’ fiber-based femtosecond laser sources integrate the latest
achievements in fiber technology into easy-to-use products. Menlo Systems’
unique figure 9® design results in reproducible and long-term stable operation. It
is based on the well-established Nonlinear Amplifying Loop Mirror (NALM) mode
locking mechanism. Both oscillator and amplifier use polarization maintaining (PM)fiber components only, ensuring excellent stability and low-noise operation. The
laser is maintenance free, user installed and ready to use at the press of a single
button. Customize your laser with the available options to match the requirementsof your application. Complete synchronization solution is available with laser andsynchronization electronics. All components from one supplier with full automation
guarantees hands off operation and more time for your experiments.
